Twenty years after the album debuted to rave reviews and heavy airplay, Soundgarden’s Superunknown is receiving a massive reissue: On Record Store Day, a set of five ten-inches compiling the records’ singles arrived; tomorrow you can purchase a five-disc “super deluxe” edition featuring B-sides, demos and rehearsal recordings via iTunes, Amazon, Best Buy and other outlets. Here, you can enter to win an Epiphone G-310 guitar that has been signed by all four members of the band.

Earlier this year, Dave Grohl recalled the moment when producer/engineer Adam Casper brought an advance of the record at Nirvana’s final recording session:

“He played ‘Black Hole Sun’ and I remember thinking, ‘Holy shit, this is gonna be huge,” Grohl recalls. “Because to me it was that perfect meeting of the Beatles and Black Sabbath, which is what I think we put in our Nirvana bio. But I don’t think that had ever successfully been paired until that record, and in particular that song. It was so much more melodically sophisticated than anything any of the other bands in Seattle were doing. It was a big deal.”
